I'm half Swiss and have hiked all over the Bernese Oberland. Every few summers, my American grandparents met us in Switzerland for a week of walking. Our most recent visit together was in 2009. For the first time, we hiked a little slower. Spent a morning on a boat instead of walking around the lake. Took the bus up the mountain and walked back down.
My grandfather still runs 5 and 10k races, but 2009 may have been the last summer of hiking together. Here they are, walking up a rocky trail, lead by my dad.
